that sucks...as it is quite a well rounded pipe on many of the Nova's...Short pipe with high fuel pressure.Gives great low end throttle response with a good top end run out. Slippery tracks its maybe too much, but if there is traction it works extremely well on the Nova's...Just in the fall time we ran a stock Keep-off 7 port on the 9886/41001 combo and it was extremely impressive on the bottom end, gobs of grunt even with a low clutch stall.With that pipe the engine feels how a ultra long stroke should feel with piles of low RPM power. On our sticky clay track surface it gives the engine tractor like low end where most other pipes seem to sap the bottom end..As counter intuitive as it sounds that pipe and header combo amplify the bottom end much more then the top end on those ultra long stroke Nova's, and visa versa with the long manifold pipe header combo's, the longer the manifold the milder the engine behaves down low
